Medical laser device

Abstract

The present invention proposes a medical laser device. A medical laser device according to an embodiment of the present invention includes a handpiece for emitting a laser frontward, the laser being received from at least one laser module for generating the laser, wherein the handpiece is configured to be grippable and includes a body having a receiving space therein and a protective cap disposed at the end of the body and formed to have a cylindrical shape such that a laser emitted from the body can pass therethrough. The protective cap is coated by a material for absorbing a wavelength of a laser emitted from the handpiece or has a filter which prevents the laser from passing therethrough and is disposed on an inner surface and/or an outer surface thereof, and is used to be replaceable according to a wavelength of a laser emitted from the handpiece.

1 . A medical laser device comprising:
 a handpiece for emitting a laser frontward, in which the laser is received from at least one laser module,   wherein the handpiece includes:
 a body configured to be grippable, and having a receiving space therein; and 
 a protective cap located at an end of the body, and having a cylindrical shape such that the laser emitted from the body is able to pass through the protective cap, and 
   the protective cap is coated with a material for absorbing a wavelength of the laser emitted from the handpiece or has a filter configured to prevent the laser from being transmitted through the filter and located on an inner surface and/or an outer surface of the protective cap, and is used to be replaceable according to the wavelength of the laser emitted from the handpiece.   
     
     
         2 . The medical laser device of  claim 1 , further comprising:
 one or more laser modules; and   a cable for transmitting lasers of the laser modules to the handpiece,   wherein the laser modules transmit the lasers having different wavelengths to the handpiece.   
     
     
         3 . The medical laser device of  claim 1 , wherein the handpiece includes:
 a guide tip coupled to the end of the body, and making contact with a procedure region to guide the laser.   
     
     
         4 . The medical laser device of  claim 3 , wherein the end of the protective cap is located higher than an end of the guide tip. 
     
     
         5 . The medical laser device of  claim 1 , further comprising:
 a guide beam emission unit for emitting a beam, in which the beam is emitted to a position of an emission target part to which the laser is to be emitted, and the beam is transmitted through the protective cap so as to be recognizable from an outside.   
     
     
         6 . The medical laser device of  claim 1 , wherein the protective cap is coupled to an end of the handpiece. 
     
     
         7 . The medical laser device of  claim 6 , wherein the protective cap includes coupling grooves formed on the inner surface of the protective cap while being spaced apart from each other by a predetermined interval in a length direction, and
 the end of the body includes protrusion parts formed at positions corresponding to the coupling grooves.   
     
     
         8 . The medical laser device of  claim 6 , wherein the protective cap includes a step part formed on the inner surface of the protective cap and stepped by a predetermined depth in an outward direction, and a step coupling part formed on the outer surface of the protective cap and stepped by a predetermined depth in an inward direction, and
 the step part of the protective cap is coupled to a step coupling part of another protective cap.   
     
     
         9 . A protective cap mounted on a medical laser device, wherein the protective cap is coated with a material for absorbing a wavelength of a laser emitted from a handpiece or has a filter configured to prevent the laser from being transmitted through the filter and located on an inner surface and/or an outer surface of the protective cap, and is used to be replaceable according to the wavelength of the laser emitted from the handpiece. 
     
     
         10 . The protective cap of  claim 9 , wherein the protective cap has an end located higher than an end of a guide tip making contact with a procedure region. 
     
     
         11 . The protective cap of  claim 9 , wherein the protective cap is coupled to an end of the handpiece, or a guide tip. 
     
     
         12 . The protective cap of  claim 9 , wherein the protective cap includes coupling grooves formed on the inner surface of the protective cap while being spaced apart from each other by a predetermined interval in a length direction, and
 an end of the handpiece includes protrusion parts formed at positions corresponding to the coupling grooves.   
     
     
         13 . The protective cap of  claim 9 , wherein the protective cap includes a step part formed on the inner surface of the protective cap and stepped by a predetermined depth in an outward direction, and a step coupling part formed on the outer surface of the protective cap and stepped by a predetermined depth in an inward direction, and
 the step part of the protective cap is coupled to a step coupling part of another protective cap.
